Answer:
The asteroid's acceleration at this point is
Explanation:
The equation that governs the trajectory of asteroid is given by :
The velocity of asteroid is given by :
At some point during the trip across the screen, the asteroid is at rest. It means, v = 0
So,
Acceleration,
Put t = 0.971 s
So, the asteroid's acceleration at this point is and it is decelerating.
Answer:
Please see below as the answer is self - explanatory
Explanation:
a) 10³ = kilo (kilogram = 10³ grams, kilometer= 10³ meters)
Symbol : k.
b) 10⁻² = centi (it is the 100th part of a unit, like centimeter, or centigram) Symbol: c.
c) .1 = deci (it is the tenth part (deci comes from the word that means "ten"in latin) of a unit: decimeter, decigram)
Symbol: d.
d) 10⁻3 = mili (it is a 1000th part of a unit: milimeter, miligram), the name comes from the word used in latin to mean "one thousand".
Symbol: m
e) 1,000,000 = 10⁶ = mega (megawatt)
Symbol: M
f= 0.000001 = 10⁻6 = micro (micrometer, microsecond),
Symbol: μ.
The correct answer for this would be "A car traveling the speed limit" this is because the car is not accelerating, and all the other answers are wrong because the objects in those are accelerating <span />
Answer:
Explanation:
Givens
m = 942
F = 6731
t = 21 seconds
vi = 0
vf = ?
Formula
F = m * (vf - vi ) / t
Solution
6731 = 942*(vf - 0)/21 Multiply both sides by 21
6731 * 21 = 942*vf
141351 = 942*vf Divide by 942
141351/942 = vf
vf = 151 m/s
D is the answer and also I love u
